Mathematical modelling and optimization of hydrogen continuous production in a fixed bed bioreactor
Contributors
Description
The purpose of this paper is to investigate, both theoretically and experimentally, hydrogen production from agro-industrial by-products
using a continuous bioreactor packed with a mixture of spongy and glass beads and inoculated with Enterobacter aerogenes. Replicated
series of experimental runs were performed to study the e6ects of residence time on hydrogen evolution rate and to characterize the
critical conditions for the wash out, as a function of the inlet glucose concentration and of the 7uid super'cial velocity. A further series of
experimental runs was focused on the e6ects of both residence time and inlet glucose concentration over hydrogen productivity. A kinetic
model of the process was developed and showed good agreement with experimental data, thus representing a potential tool to design a
large-scale fermenter. In fact, the model was applied to the optimal design of a bioreactor suitable of feeding a phosphoric acid fuel cell
of a target power.
